Compare the public keys between nodes, they are probably different .( only 1 node is up on my RAC right now so cannot check)

Here is one simple method to fix it.

node1:

append to the end of ~/.ssh/authorized_keys the value of the public key from the same directory
this will be a file called either id_rsa.pub or id_dsa.pub, but probably an RSA key.

node2:

do the same as on node 1
